1. Periodic Trends - Warmup
Ca2+ and K+ each have 18 electrons around the nucleus.
Which has a smaller radius and why?

2. Warmup - Overview of PT
From memory, compare metals, metalloids, nonmetals (see samples at Station 8) and noble gases in terms of:
Appearance
State of matter
Electrical conductivity
Heat conductivity
Malleability and ductility
Atomic radius
Ionization energy
Electronegativity
Electron configuration
